We measure neutrino charged-current quasielasticlike scattering on hydrocarbon at high statistics using the wideband Neutrinos at the Main Injector beam with neutrino energy peaked at 6 GeV. The double-differential cross section is reported in terms of muon longitudinal ($p_{\parallel }$) and transverse ($p_{\perp }$) momentum. Cross section contours versus lepton momentum components are approximately described by a conventional generator-based simulation, however, discrepancies are observed for transverse momenta above $0.5\mathrm{GeV}/c$ for longitudinal momentum ranges 3–5 and $9–20\mathrm{GeV}/c$. The single differential cross section versus momentum transfer squared ($d\sigma /d{Q}_{\mathrm{QE}}^2$) is measured over a four-decade range of $Q^2$ that extends to $10{\mathrm{GeV}}^2$. The cross section turnover and falloff in the $Q^2$ range $0.3–10{\mathrm{GeV}}^2$ is not fully reproduced by generator predictions that rely on dipole form factors. Our measurement probes the axial-vector content of the hadronic current and complements the electromagnetic form factor data obtained using electron-nucleon elastic scattering. These results help oscillation experiments because they probe the importance of various correlations and final-state interaction effects within the nucleus, which have different effects on the visible energy in detectors.

烃靶上6 GeV的中微子准弹性样散射的高统计测量。

我们在主注入器束中使用宽带中微子，中微子能量峰值为6 GeV，以高统计量测量碳氢化合物上的中微子带电电流拟弹性散射。双微分横截面以μ子纵向（$p_{\parallel }$）和横向（$p_{\perp }$）动力。横截面轮廓与轻子动量分量的近似关系通过常规的基于发电机的模拟进行了描述，但是，在上述横向矩上观察到差异$0.5\mathrm{GeV}/C$ 对于纵向动量范围3-5和 $9–20\mathrm{GeV}/C$。单个微分截面与动量传递的平方（$d\sigma /d{问}_{\mathrm{量化宽松}}^2$）的测量范围是四个十年 ${问}^2$ 延伸到 $10{\mathrm{GeV}}^2$。横截面周转和下降${问}^2$ 范围 $0.3–10{\mathrm{GeV}}^2$依赖偶极子形状因数的发生器预测不能完全再现这种现象。我们的测量可以探测强子电流的轴向矢量含量，并对使用电子-核子弹性散射获得的电磁形状因子数据进行补充。这些结果有助于振荡实验，因为它们探测了原子核内各种相关性和最终状态相互作用效应的重要性，这些效应对探测器中的可见光能量具有不同的影响。
